In this article, we will discuss the Hypertensive Emergency. So, let’s get started.
According to JNC (Joint National Committee) VI report, a hypertensive emergency was defined as a severely elevated BP diastolic >130 mmHg with signs or symptoms of acute target organ damage (e.g. eye- hypertensive retinopathy, papilledema, kidney- renal impairment or failure, blood vessels- peripheral vascular disease, etc), requiring parenteral drug treatment, close observation in ICU and immediate reduction of blood pressure (within one hour) to avoid risk of morbidity or death.
